COMPOSITION FOR FINISHING WALLS.

No Drawing.

To aZZ whom it may concern Be it known that I, ROBERT M. CRAIG, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Compositions for Finishing Walls, of which the following is a specification.

The invention relates to compositions for finishing the exterior and interior of walls and ceilings and has for its object the provision of a composition that not only gives an ornamental finish to the walls but also makes said walls impervious to moisture.

In preparing my composition I take onehalf pint of powdered mineral wax, one quart of cement, which may be gray La Farge Portland cement or Atlas white stainless Portland cement, in accordance with the color that I desire to have the composition when completed, one pint of ordinary table salt, one quart of saturated solution of Washing soda and mix these ingredients with one and three-quarters gallons of hot water, the hot water being required in order to melt the wax and cause it to thoroughly mix with the other ingredients.

This composition may be applied to the exterior walls ofthe building or may be applied over the rough plaster coat on the interior walls and ceilings, the application being made first with a brush and then rubbed down with burlap or suitable rough fabric.

The composition is not only ornamental but renders the walls impervious to moisture.

Copies of this patent may be obtained for Specification of Letters Patent.-
